1st) ALTERNATIVE

1. Move the cur­sor over the spot you want coor­di­nates for.
2. Right click and select “Direc­tions to here” on pop-up menu.
3. Copy coor­di­nates from “End Address”: e.g. 29.199505,-90.041242
4. Paste them back into the “Search Maps” box and click to check position
and get them in DMS for­mat: e.g. +29° 11′ 58.22″, ‑90° 2′ 28.47″

2st) ALTERNATIVE

You can also use the ‘Link to this page’ in the upper right hand corner.
I usu­al­ly right-click on point of inter­est and ‘Cen­ter map here.’
Then choose the ‘Link to this page’ option.
You should be able to copy and paste the URL and extract the coor­di­nates from there.
